A JK sitting on a 4.5 in lift needs rear damping sized for that height or the back end gets harsh and loose on washboard. The BDS NX2 Nitro rear shock is built for a 4.5 in lift and uses a nitrogen-charged twin-tube design with 10-stage velocity-sensitive valving. Polyurethane bushings and metal sleeves come with it for the swap.
